Sometimes it is really difficult to predict the result of a match. Like in the Real Sociedad - Villarreal example.

I wanted to trust Real Sociedad with my bet on them but I wish I didn't. It was a really big home defeat.
Today Barcelona and Atletico Madrid look highly favorite in their games but I don't know whether it is a good idea to bet on both of them. I'm not intending to do it actually after seeing the odds (1.75) given to Atletico Madrid. Isn't it too high?

I remember this scenario from an away game against Las Palmas. I might turn out to be right about doubting this one also. I'm not placing a bet on Atletico Madrid to win as a result.
Matches like yesterday at Real Sociedad are some kind of exception to the rule, they dominated, but Villarreal scored, who made 4 shots on target and at the same time managed to score 3 goals. Yes, sometimes this is possible when a motivated team loses a home match. But on the other hand, Villarreal is not a weak team, although they are having a weak season, they have very good players who can decide the outcome of the match.
